Help me identify this engine
Hi
Can someone help me identify this engine? Also what are the two nozzles in the belly just beneath the cylinder for seems like these are for oil radiator to cool down oil. Can I get its service manual? Last edited by Lkhangee; 04-09-2018 at 09:47 PM. |

That is an unusual animal. The Q in the serial number implies air cooling, but those ports certainly look like they connect to an oil cooler. The rest of the numbers don't really make sense, and it seems like it is claiming 150cc displacement. If that's true, there is no need for oil cooling; you could simply connect the two ports with a hose and clamps.
The engine is the CB design, which is most commonly CB200 or CB250 in North America. They are quite similar to the Honda CRF230, so any tuning specs from that should cross over.

These things never came here. It e only few items. I need its service manual and can someone point me to some documents or resources that explains this engine working. And what are the two nozzles in its belly just beneath the cylinder? Climate here is mostly hot. Summer Temps raise above 45 degrees Celsius coupled with jam packed third world traffic and roads with average speed in single figures. |

=== Dark history of Qingqi http://www.lnmoto.cn/bbs/thread-776216-1-1.html They used build oil cooled bike from Hyosung parts... Korea is just across the sea from that province. Many Korean product are smuggled/imported via https://en.wikipedia.org/wiki/Chinese_people_in_Korea their homeboy ...  Anyway ethnic Koreans https://en.wikipedia.org/wiki/Koreans_in_China don't had those chance...

For current engine it already have two nozzles under the cylinder for oil cooler. Any idea how big radiator can I use. I was thinking to use Hayden rapid cool radiator from a jeep. It has 300ml capacity. Also is there secondary pump specific for that two nozzles? Or is it same pump? Would redirecting oil flow via that affect the oil flow volume /pressure inside to other parts? |

300ml ?! Google translate http://ku-motor.blogspot.com/2014/08/blog-post.html will tells something
CB (ohc) type w/o blocked some oil path or upgrade oil pump (Lazy folks often choose electric pump.), the head may NOT have enough oil (Worst shit in these engine)
